"Dust II", also known by its filename de_dust2, is a video game map featured in the first-person shooter series Counter-Strike. Dust II is the successor to "Dust", another Counter-Strike map, and was developed by David Johnston before the official release of the original Counter-Strike game. It was designed with the aims of simplicity and balance, based on its symmetrical design and two points, over which the two teams must fight for control.

In video games, a level is any space available to the player during the course of completion of an objective. Video game levels generally have progressively increasing difficulty to appeal to players with different skill levels. Each level may present new concepts and challenges to keep a player's interest high.
